Abstract

The main purpose of this thesis was to obtain the symbolic solution of a multilayer
(four fluid media) ocean waveguide problem. The waveguide was assumed to have depthdependent
ambient density and sound speed profiles in all fluid media, and arbitrarily
shaped boundaries between all fluid media. A system of 28 equations in 17 unknowns
was generated by satisfying all of the boundary conditions (including the boundary
condition at the source) in cylindrical coordinates. The problem was set up as a
weighted least squares problem for symbolic solution by the computer program Mathematica,
Due to software and hardware constraints, a symbolic solution for the most general case
was not obtained. However, by making all of the boundaries plane, parallel boundaries,
two cases were successfully programmed, yielding symbolic solutions which were verified
by comparison to previously known results.

The purpose of this research is to identify how the Improvised Explosive Device (IED) is being used as a "weapon of strategic influence" by insurgent groups in Iraq. It is intended to explore how individual IED events, ...

High speed oscillatory flows, like high speed mean flows, are capable of inducing time-averaged heat transfer effects. This research involves the analytical solution of a model problem of zero-mean internal oscillatory ...

This paper presents a boundary-layer model to predict dynamic characteristics of liquid motion in partially filled tanks of a spinning spacecraft. The solution is obtained by solving three boundary-value problems: an ...
